Small Parts - 29201 Carbon Steel Internal Retaining Ring Assortment (150 Pieces), Zinc Plated Finish, Inch, With Case

The 150-piece zinc plated carbon steel internal retaining ring assortment includes housing rings in various sizes and comes in a compartmented plastic case for storage and organization. The tapered design maintains constant pressure to prevent slippage of axles, gears, and bearings inside machinery housing. The rings are made from carbon steel, which offers flexibility and a balance of strength and toughness. The material is magnetic. The zinc plating offers corrosion resistance and a reflective appearance.Retaining rings attach to a shaft (external) or install in a bore (internal), creating a shoulder to maintain component positioning within an assembly. While most rings install into a machined groove either on the inside or outside diameter of a shaft, self-locking rings attach to a shaft by using friction from means such as teeth and notches to maintain placement. Retaining rings should fit tightly enough into the groove or onto the shaft so they won't experience any movement.What's in the Box?(15) 1/2" internal retaining rings(15) 5/8" internal retaining rings(15) 11/16" internal retaining rings(15) 3/4" internal retaining rings(15) 13/16" internal retaining rings(15) 7/8" internal retaining rings(10) 1" internal retaining rings(10) 1-1/16" internal retaining rings(10) 1-1/8" internal retaining rings(10) 1-1/4" internal retaining rings(5) 1-3/8" internal retaining rings(5) 1-1/2" internal retaining rings(5) 1-5/8" internal retaining rings(5) 1-3/4" internal retaining rings(1) plastic case
